Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) passed by a man who had placed his foot on the side of a goat while he was sharpening his knife, and the goat was watching him with its eyes. He (peace and blessings be upon him) said: "Could you not have done this before? Do you want to make it die twice?"
